BRUSSELS, Oct. 25 (Xinhua) -- The Grand Duke Henri of Luxembourg on Friday tasked Xavier Bettel, Luxembourg city mayor and leader of the Democratic Party (DP) to form the next government, sidelining long-serving Prime Minister Jean Claude Juncker.
Bettel, whose party took 13 seats in the 60-member parliament in elections earlier this month, is set to form a government with the Greens and Socialists, the palace said.
Juncker's Christian Social Party (CSV) won 23 seats during the election, the Socialists took 13, while the Greens took six. The last five seats are shared by two other smaller parties.
Veteran eurozone dealmaker Juncker had been Luxembourg premier since 1995 and had served in Luxembourg's government since 1982. The CSV party, meanwhile, has been in power for all but five years since 1944.
But opposition parties have announced they want to create a tricolor alliance - red for the Socialists, blue for the DP and green for the environmentalists - against the "monopartism style" of the CSV.
A coalition of three parties will be "very difficult, because of their differences" in political programs and between their leaders, especially between Bettel and Socialist leader Etienne Schneider, said Michel Reiland, CSV legislative candidate.
The CSV has been the dominant partner in governing coalitions for decades.
Juncker submitted his resignation to the Grand Duke in July, when a probe concluded that he failed to inform the parliament of irregularities and illegalities conducted by the country's secrete services between 2004 and 2009.
Juncker denied any wrongdoing, but his CSV party lost confidence in the parliament when the center-left Luxembourg Socialist Workers' Party (LSAP) withdrew from the CSV-led coalition government over the scandal.
